If there is 11 protons then that would be Na or Sodium.
No. sodium is an alkali metal element that has 12 neutrons, 11 protons and 11 electrons in it's compositional make up.
The element with one less proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12.
The element with one more proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12 protons.
That depends on which isotope of sodium you are talking about. Sodium always has 11 protons. The atomic mass of sodium is about 23, meaning there are, on average, 12 neutrons, so the average neutron to proton ratio for sodium is 12:11.
It has similar properties to the element with proton number 20, which is calcium.
proton and neutron
It is a 1:1 ratio because in a Carbon-12 atom there are 6 neutrons and 6 protons.
sodium-11 has 5 proton,5 electron and 6 neutron. hahaha...miss-a--danq2,cia2,stephai,trinang!
The mass of 12 protons is approximately equal to 12 atomic mass units.
Sodium-12 (Na-12) has 12 nucleons in total, which includes both protons and neutrons. Sodium has an atomic number of 11, meaning it has 11 protons. Therefore, the number of neutrons in sodium-12 is calculated as 12 (total nucleons) - 11 (protons) = 1 neutron.
Magnesium has an atomic number of 12, therefore it has 12 protons, and therefore 12 electrons.
Because proton and nelutron present in nucleus with charges positive and negative while neutron have no charge and proton and electron have same in numbers and the ratio have between electron and is zero. For.eg magnesium have 12 atomic number and proton and are also 12 in magnesium there ratio is 1:1
